Problems with Int32MultiArrays

edit

Hi,

I'm wondering if anyone knows what these errors mean:

My code is really long to post, so I was wondering if there was something general that these are getting at that I can look out for in my code.

I'm trying to pass std_msgs::Int32MultiArray::ConstPtr& arrays from a subscribed topic into a function to pull out the data.

Any help on this would be greatly appreciated!!

Edit: I am running ROS electric on Ubuntu 11.10.
